Selling bed linens in her little shop in Dingle by day and Ireland’s most accomplished ice and extreme swimmer by night, Nuala Moore is a force to be reckoned with.

Dingle’s Nuala Moore is a veteran ice swimmer. To mention just a few of her accomplishments: She is one of only six people to swim around the coast of Ireland in a 1,330km relay over 56 days. She then did a double-crossing Relay of the English Channel and swam the Bering Strait from Russia to the USA in some of the most dangerous waters in the world in a relay. She was the first Irish swimmer and the sixth woman in the world to complete a 1000 metre swim at 0 degrees in the Arctic Circle. Her latest challenge will see her head to the ‘end of the world‘ to swim in the waters where the Pacific Ocean meets the Atlantic Ocean. She will (if all goes to plan) follow this up with a solo double crossing of the Beagle Channel!

As I waited for my first Social Security check, I decided to push the envelope with swimming, a sport I had practiced for six decades. I read about the Gibraltar Crossing and realized that the idea of swimming from Spain to Morocco allayed my worries about turning 70. For me, when I am in the sea, all is well with the world.

It all started inauspiciously at the Bowman Gray pool, an ancient structure at the University of North Carolina. I was four and my swim teacher was squeezing my chest too tightly. Later that day, my mother yelled, “You bit his wrist like a damned dog. What a mean boy you are!”

Escape from Alcatraz: Does letter finally solve mystery of prison's most infamous escapees?

A letter has emerged allegedly revealing the fate of three criminals who pulled off a historic escape from Alcatraz and disappeared without a trace more than 40 years ago.

On the night of 11 June 1962, brothers John and Clarence Anglin and fellow inmate Frank Morris pulled off a prison break so daring it went on to inspire Hollywood thriller Escape from Alcatraz, starring Clint Eastwood.

In order to preserve marathon swimming history, Dale Petranech has kept alive his dream of publishing the personal files of World Professional Marathon Swimming Association administrator, Joe Grossman.

"Joe passed away in 1974, but Dale faithfully maintained a huge stack of type-written pages from Joe for several decades.

The public information officer traveled around the world with a passion and a unique perspective of the individuals involved in the sport of channel swimming and professional marathon swimming and single-handedly and comprehensively compiled hundreds of pages of notes, observations, recollections and data from solo swims and competitions in numerous bodies of water around the globe," says Steven Munatones.

32-year-old finished the marathon by swimming across Cook Strait between the North and South Islands of New Zealand in 8 hours 37 minutes

The sea is as perilous as it is calm. And, no one knows that better than Rohan More who became the first Asian to swim across seven of the world's toughest ocean channels this month. On February 9, the 32-year-old resident of Senapati Bapat Road in Pune, swam across the Cook Strait between the North and South Island of New Zealand in 8 hours and 37 minutes. The Ocean Seven, a marathon-swimming challenge consisting of seven channel swims, is considered equivalent to the Seven Summits mountaineering challenge, that involves scaling the highest mountains on each of the seven continents. He is only the ninth person to complete it.
